Behavior question

Well now it's one of the ones that is assigned at startup - it wasn't when
I started this thread.  I'm pretty sure this all has to do with the
engine's resolution of behavior references happening before all stacks are
loaded.

I have all my behaviors in a separate mainstack which is opened in a
preOpenCard handler of the stack whose controls reference the behaviors.
It appears even preOpenCard doesn't happen soon enough to allow the engine
to resolve the behavior references.

I wonder if putting a reference to the behaviors stack in the application
stack's stackFiles property would fix this.  I will try and post the result.
